Good cleaning is the trick when spraying vinyl. You'll have to remove whatever vinyl dye is on there now.

You could try cleaning the vinyl first with a good degreaser, such as Purple Power or equivalent. I prefer not to use lacquer thinner to wipe vinyl. It's too aggressive and dries quickly, often leaving a film behind which could be your culprit causing fisheye. After cleaning with a degreaser, wipe it down with a paint prep solvent instead.
Then, spray it with SEM Vinyl Prep spray. This will further clean & soften the vinyl so the dye will stick better. Read the can. Spray it, let it sit, then wipe dry. Then, use the dye.
Hope that helps some.

Fish eyes are generally caused by moisture. Are you using spray cans or a real 2 or 3 part product?

Silicone will cause fisheye as well, as does citrus which include many hand soaps and the actual fruits so make sure you haven't used any of that stuff where you are about to paint and make sure it's not on your clothing or rags laying around.  Try to build a small paint booth out of some cardboard to minimize contaminants in the area.  Clean with a degreaser but use tsp and water if you need to.  Spray the first coat real thin.  If fisheye still forms it'll be tiny and you may be able to save it.

Fish eyes are caused by contaminants on the surface: oils, grease, silicone, etc. Simple things like oils on your skin will cause fisheye.
Moisture will usually cause small bumps in the paint similar to solvent pop, or defects later on as it dries or cures. Or, hazy paint & dieback.

Another tip: wear rubber gloves!
